Kaethe Danziger (geb. Halberstaedter) names her as Elise Osterman and mentions Berlin.

Her marriage certificate names her parents as Jacob and Babette geb. Halberstadt.

Elise appears in the Berlin address books in 1931, 5 years after her husband's death (the address continued to appear in Bruno's name until 1930).

The 1939 census of Berlin lists her at Karl-Schrader-Strasse 6, an address she shared with (among others):
- her brother Wilhelm Ostermann,
- his wife Dora Ostermann geb. Heilbronn,
- her mother Valeria Heilbronn geb. Seligsohn.

Elise emigrated to the Netherlands in August 1938 and was recorded in Bennekom at De Heid, 25 in May 1941.

Yad Vashem records that she spent the war in the Netherlands and was deported from Westerbork transit camp to Sobibor extermination camp where she was murdered on 23.04.1943.

She is commemorated by a Stolperstein in Berlin.
